Abstract

1,088,106. Permanent-magnet generators. ELECTRIC CONSTRUCTION CO. Ltd. June 23, 1965 [June 23, 1964], No. 25915/64. Heading H2A. [Also in Division F1] An inductor-type tacho-generator consists of a pair of forked cores 5, 6 excited by a magnet 4 and co-operating with a toothed rotor 1 to energize a pick-up coil (not shown) round the inner limbs 8, 9 of the forks. The inductor rotor 1 may form part of the fan of an induction motor (Fig. 3, not shown). There is a keeper 11.
